UNITED STATES PATENT OFFICEe WILLIAM M. GRAZE, OF LOG'ANSPORT, INDIANA, ASSIGNOR 'TO HIMSELF AND NEWTON W. TAYLOB, OF CLEVELAND, OHIO, ONE-HALF TO EACH.

PLASTlC COMPSITION FROM PAPER-PULP FOR FLOORS, BRAKE-SHOES, JOURNALS, &0.

SPECIFICATION forming part of Letters Patnt No. 239,951, dated April 12, 1881.

Application filed September 14, 1880. (No model.)

To all whom it mayconcern:

` Be it known that I, WILLIAM M. GRAZE, of Logansport, in the county of Cass and State of Indiana, have inVented certain new and useful Improvements in Plastic Compositions from Paper-Pulp for Floors, Brake-Shoes, J ournals, &0.; and I do lereby declare the following to bea full, clear, and exact description of the in- Vention, such as will enable others skilled in iro the art to which it pertains to make and use it, reference being' had to the accommnyng drawings, which form part of this specification. My invetion relates to a new compound or composition of matter; and it consists, broad- 1 ly, in a mass composed of a mixture in suitable proportions of paper-pulp and metallic filings,`said mass being' brought to any desired consistency orsolidity by pressure.

The uses to which my product can be put are manifold ouaccoutof its excee'dingtoughness and durability, its resistance to decay M and climatic influence, its heat and sound nonconducting qualities, and its quality ot' very slight expansion and contractiou from heat and cold. On account of its elasticity it will he found useful in all places where the wear of frictiou is to be resistedsuch as journals brakeshoes, shuttle-carriers, &e lt is' also well adapted for use in the Construction of floors, and a floor made or covered with my product can be as ornamental as taste may dictate, while at the same time it is always warm and a non-conductor of sound.

To make my product paper-pulp of any description is mixed with metallic filings in any suitable proportion, the relative proporiions of the paper-pulp and metallic filings being governed by the particular use to which the product is designed. The pulp and netallic `filings may be mixed together in any suitable way, and when mixed the mass is m'olded or pressed into any desired form-such as sheets or plates, journal-boxes,floor-tilings, or into any otherform desired. If used forfloor-tiliu gs,

' any color-ing pigment or dye maybe added for the sake of beauty.

lf the product is to be exposed to moistnre or climatic influence, there may be added any i protecting or antisep tie ingredient such as d 0 paraffine resin, or oil.

I do not limit myself in any degree to the use to which my invention cau be put, and my invention not only comprehends .the product lerein described, but anything constructed from said product.

The toughness or hardness of said product depends upon the pressure to which it is subjected,` and this may be suitably proportioned for anyparticular use to which the finished product is designed.

It is evident that in some cases my product would enter as ani'gredient of other compositions of matter, and for certain purposes additional snbstances can be added for particular uses to which the finished productis to 'ne put.

My product, as already intimated, may he made from a nixture of metallic filings and paper-pulp, with or without a sizing of oil, resin. paraffine, or equivalent substance.

l have specified netallic filings as one of the ingredients of my mass. Instead ot' metallic filgs, pnlverized ore might in some cases be substituted thcret'or.

In the dranings, Fignre l repesents in plan View a tloor; Fig. 2, a wheel-brake shoe; and Fig. 3, a portion of ajournal-box, all ot' which may be formed from my composition herein specified.

What I claim is l. A composition of matter consisting of a mixtnreofpaper-pulp and metallic liliugs, (with or without a sizing ot' oil, resin, parafine, or

'the like,) substantially as specified.

2. As a new article ot' manufactnre, the. product obtained by mixing paper-pulp and me tallic filings together (with or without a sizing of oil, resin, paraffiue, or the like) and subjectig the same to pressure, snbstantially as specified.

3. As an article of manufactnre, fioor-tilingy journal-boxes, shuttle-carriers, or any other thin constructed from a mass consstin of a b b mixture of pap'er-pulp and metallic filings (with' or without a sizing of oil, resin, paraffine, or the like) solidified under pressure, substantially as specified.

In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM M. GRAZE.
